SPECIFICATION forming part of Letters Patent No. 506,540, dated October 10, 1893.

Application led February 10, 1893. Serial No. 461,779. (No model.)

To all whom it may concern,.-

Be it known that I, LEWIS A. PARK, of Townsbury,'in the county of Warren and State of New Jersey, have invented a new and Improved Elevator and Conveyer, of which the following is a full, clear, and exact dedesired point, and the object of my invention is to produce a simple, strong and eective machine of this kind, which is readily moved from place to place, which enables articles of the kind described to Vbe conveniently raised,

which has means for depositing said articles in the exact place required, which is provided with an adj ustablel system of braces adapted to greatly strengthen the extended portions ofthe machine, and which has a horizontal pivoted track and carriage adapted to convey the raised material and adapted also to be swung into line with the body of the vehicle of which the machine constitutes a part, so that when the machine is hauled about it will be in a very compact shape.

lTo these ends, my invention consists in cerftain features of construction and combina- 3- tions :of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part o f this specification,

nection between the `trac); beam, ythe swingin which similar figures of reference indicate corresponding parts in all the views.

Fig. ll is a sectional elevation of the same, on the line ll-ll in" Fig. l0, showing also a side elevation of the carriage. Fig. 12 is a detail sectional View on the line 12-12 in Fig. `l0, illustrating the locking mechanism for securing the carriage operating gears. Fig. 13 is a broken detail front elevation of the connected portions of one of the extensible braces, showing particularly the gear mechanism for extending the braces, and the pawl for locking the vgear mechanism. Fig. 14 is a sectional elevation of the gear connection between the parts of one of the extending braces; and Fig. 15 is an end view of a preferred form of track for the carriage.

The machine is provided with an upright frame l0, of a generally rectangular shape, which frame is supported on a bed 11 and braced by braces l2, and the bed 1l is pro.

vided with wheels 13, like an ordinary vehicle body.

On the front and back portions of the frame l0, at a point near the top and parallel with the top, are cross beams 13, and eachbeam connects with the top of the frame above it by a post 14, the-post being placed oft the center, as shown best Ain Figs. 3 and 5, one post being on one side of the center and the other on the opposite side, so as to provide for the swinging of the track beam as hereinafter described.

The `track beam, which will be described below, is held centrally on the frame and is adapted to be turned horizontally into line with the bed 1l, or at right angles to the same, and consequently it is necessary to provide openings in diagonally opposite corners of the frame, and to this end, one corner oftheframe on the front side and the opposite corner on the back side, have a removable post 15 which extends from the cross beam 13 to the top of the frame 10.

The post l5, which is shown in detail s.in Fig. 8, has on its outer side a plate 16, which overlaps the upper and lower portions of the IOO in the projecting ends ofthe plate are holes 17, which are adapted to receive pins 18 on the upper and lower portions of the frame 10, as illustrated in Fig. 4. Each post is locked in place by a bolt 19, which extends downward through the top of the frame through a longitudinal hole in the`post 15, and into a nut 2O which is heldin one of the posts of the frame 10.

lThe track beam 2l is a long beam capable of extending well out from each side of the machine, and it ispivoted in the center on a bolt 22, and on the under side and central portion of the top of the frame 10, as clearly shown in Fig. 11. Thetrack beam is strengthened by a brace 23, which extends over the top of the frame and is bent downward at its ends and formed into flanges 24, which are bolted to the beam. The brace 23 is also pivoted on the bolt 22, and between the brace and the frame 10, is a broad washer 25.

It will be seen from the foregoing description that the track beam may beheld in a line parallel with the length of the bed l1, and that by removing the posts 15, it may be turned into a position at right angles to said line. Y

On the under side of the beam 21, is fastened a flat plate 26, which projects from opposite sides of the track beam, as shown in Fig. 9, and which serves as a track on which the conveying carriage 27 runs.

' The preferred form of track is shown in Fig, 15, andv this form has angle irons 26a bolted to opposite sides of the beam 21 so as to fit snugly against the beam and against the plate 26. 'lhe carriage consists of a flat plate having up-turned side flanges 28, which have on theirinner sides rollers 29, and these run on the track plate 26, and the carriage 27 is thus hung so as to travel beneath the track.

T-he carriage 27 is provided with a swivel hook 30 on its under side to which a hoisting device 31,wl1ich may be of any approved construction, is attached, and the hoisting device is thus always beneath the carriage and in position for use. The carriage has at opposite ends hooks 32, which are secured to lugs 33 on the carriage, and these' hooks are fastened to the ends of achain 34, by which the carriageis moved. y

The chain 34 extends longitudinally around the track beam, it being carried over sprocket wheels 35 which are journaled in the ends of the beam, thence over sprocket wheels 36, which are journaled in hangers 37 on the brace 23, thence over a sprocket wheel 38, and under a driving sprocket wheel'39,these latter wheels 38 and 39 being journaled in hangers 4() on thel brace 23, and being arranged one above the other but in different planes. i

-The sprocket wheel 391s carried by a shaft 4-1 (see Figs. 10 and 11) and this shaft is provided with a relatively large gear wheel 42, which is driven bya small gear wheel or pin ion 43 on the shaft 44, which shaft is provided at its outer end with a crank 45 by which it may be turned, and it is journaled at its inner end in the hangers 40, and at its outer end in a box 46 carried by an outwardly-extending brace 47, which is rigidly attached to the brace 23.

The object of having the shaft 44 and its supporting brace 47 prolonged, is to enable the crank 45 to be brought into position above the operating platform when the machine is used as will be presently described. It will be observed that by turning the crank 45, the gearwheels 43 and 42 are turned and movement imparted to the chain 34, so that the hoisting device 3l may be brought into any necessary position beneath any part of the beam 21.

The chain 34 and vthe carriage connected with it are held in position by locking the,

gitudinally of the carriage, it maybe locked in place by bolts extending through the beam 21, and through lugs 51 and 52 on the frame 10, and when the beam is turned so as to extend transversely across theframe, it may be locked by bolts extending through it and through lugs 51a on the sides of the frame 10.

When the machine is used for hoisting and conveying, the beam 21 is always at right angles to the main portion of the carriage, and when in this position, the operating crank 45 comes directly above a platform 53 on the front side of the frame 10, as shown in Fig. 5, and the operator or operators stand upon this platform to work the machine. vIt'is obvious that where a heavy load is to bek ca'rried to one end of thebeam 21,the beam will require efcient bracing, and to this end, the braces described below are employed. The beam 21 has at its endsstrong cross braces 54, which are adapted to receive sockets 55 on the free ends of swinging side pieces 56, the sockets being locked to the cross pieces by pins 57, and the side pieces are hinged at IOO their lower ends to the lower portion of the frame 10, as shown at 58 in Fig. 5; consequently, when the side pieces are swung outward and the sockets 55 locked to the cross pieces 54, the side pieces will extend in a diagonal direction from the frame,and will assist in supporting the beam 2l. When, however, the side pieces are not in use and the machine is to be moved, they are swung into a vertical position against .the sides of the frame 10, and they are held in this position by means of hasps 60 ontheframe which engage eyes or staples 59 'on the-side pieces.

ISO

To further brace the beam extensible braces 61 are used, whichare adapted to extend from the cross pieces 54 to the ground, and these extensible braces should extend in a direction approximately at right angles to the di` rection of the side pieces 56, as shown clearly by the following mechanism; the section 62, of the brace is provided with a rack 67 near 4its lower end, and journaled in a supporting block 68 on the section 63, at a point which overlaps the rack, is a gear wheel 69, which is turned by a crank 70, and is held in a slot 71 made in the block 68 and section 63, so

that the gear wheel meshes with the rack. Itwill be seen thenV that by turning the gear' 'wheel, the sections 62 and 63 may be moved in relation to each other and the length of the' brace 61 regulated. The two sections of the brace 61A are held in a xed position in relation to each other bya pawl 72, which is pivoted .near the center, as shown at 73 in Fig.

13, on the block'68, and the pawl has at one end a handle 74 by which it may be conveniently moved. The opposite end of the pawl is adapted to engage the gear wheel 69 and- Thev pawl -is curved' on onelock the same. side so that the curved portion projects beyond the side of the brace, as .shown at 75 in Fig. 13. In this curved portion are notches 76, which are adapted to engage a spring 77 on the side of the section 63 (see Fig. 14) and the pawl may be locked either into or out of engagement with the gear wheel by this spring, according as to whether the brace is to be extended or to be locked in a fixed position. It will be readily seen then that each brace 61 may be made of any necessary length and lockedrigidly so as to be as strong as a solid brace, and it will be seen that the brace 61 and side pieces 56 makea very strong support for the beam 2l, so that a rock or other article of great Weight may be carried to the extreme outer end of the beam without tipping .the machine in the least.

When the machine is to be used, it is drawn into position above the rock or other article to be handled andadjacent to the Wall or other place into or on which the article is to be deposited. The posts 15 are removed, the beam 21 turned into a position at right angles to the length ofthe machine so that one end of the track beam will extend above the wall or other point where the article is to be deposited; the beam is fastened in place in the manner described. The posts 15 are replaced, the side pieces 56 swung outward and placed in engagement with-the cross pieces 54. The braces 61 are placed in position to support the outer ends ofV the-beam, although it is usually necessary to use but two braces at a time as only one side of the machine needs supporting. The article is then lifted by means of the hoisting apparatus 3l, and

the operators standing on the platform 53,

turn the crank 45, thus moving the Vcarriage 427, and the article is carriedl to the desired point at one side of the machine where it may be deposited. A

When the machine is to be moved, the track beam is fastened in place so as to extend longitudinally of the machine, the side pieces 56 are held in a vertical position against the machine frame, .and the braces 61 may be laid upon the bed 11 and within the frame 10, as shownin Fig. 3.l
